Why It’s Important To Keep Trailer Tires Properly Inflated

Frequently Asked Questions

What PSI should I run my trailer tires at?

Boat-trailer tires require a lot of air pressure — in most cases, between 50 and 65 psi. In fact, the correct tire pressure for your boat trailer is almost always the maximum-rated pressure for that tire, which is molded right on the sidewall. Maintaining that trailer tire PSI is critically important to towing safety.

Should I run my trailer tires at max PSI?

A trailer tire should be inflated to the maximum inflation designated on the sidewall of the tire to provide the full load carrying capacity. The best time to check the air pressure is when the tire is cool to the touch, and not right after the tire was in operation.

What PSI should my all terrain tires be?

Somewhere in the range of 26psi to 32psi is usually about right for rough gravel. If you were running 38psi on the road, then drop pressures to 32psi on rough gravel and see how it feels. If you were running 30psi on the road then 26psi might be appropriate on crook gravel roads and tracks.

Should I cover my trailer tires?

Over time, ultraviolet rays from the sun cause tire compound to break down. When parked outside, cover your trailer tires with tire wheel covers or UV reflective material. ... If nothing else, park your trailer in the shade. Be aware, however, that your tires can still get a good dose of ultraviolet rays in the shade.

What should the tire pressure be in a travel trailer?

For most travel trailers, the tire pressure is mostly between 40 psi to 65 psi. Remember, this is not what you have to set, its what the average numbers look like. That is, most travel trailer tires will be inflated with PSI falling in this range.

How big of a tire can I fill with 35 psi?

That is the size you will want to stick with. Any given size tire can have different load ranges. For example an ST175/80-13 load range B will have a capacity of 1,100 pounds at 35 psi. But a load range D in the same size, # AM10210, is rated for 1,610 pounds at 65 psi.

What's the Max tire pressure for a P-Metric tire?

So for our P-Metric P275/65R18 tire the sidewall says Max Load is 2601 lbs. and Max Pressure is 44 psi. Question: From the 91% Rule above, if I want to ensure the tire can carry 2,367 lbs. capacity, then should I inflate the tire to the Max Pressure of 44 psi per the sidewall of the tire? Answer: NO!

What's the maximum pressure for an extra load tire?

Extra Load tires of the same size will typically have the same load capacity at the same pressure as the Standard Load tire. However, they have added load capacity above certain pressures. Light and Standard Load tires have a maximum capacity pressure rating of 35-36 psi and Extra load tires have a maximum capacity pressure rating of 41-42 psi.
